Good deal. Did you happen to smell gas when you drained the oil? I would bet gas had seeped past the carburetor while sitting for 2 years and found it's way into the crankcase. I know, it has happened on my GY6 quad while sitting over winter.

The sound seems to be in time with the exhaust note. Going by that, I would suspect a exhaust leak. I would verify that you have a good seal at the exhaust port on the head. I find wiggling the exhaust pipe as you tighten the flange bolts helps to get the gasket surfaces to mate up right. Again you want to tighten one bolt a little and then the other until they are snug. Also, loosing the muffler mounting bolts helps with getting the exhaust gasket to seal proper. It allows everything to move so you get a good seal. Just don't forget to retighten them up. Good luck.

My turn signal broke too. The center cancel button popped off somewhere. At least they are reasonably priced.
I have a BWS windshield on it's way. I hope it makes the colder commutes a bit better by keeping the wind off me more. My coldest ride so far was yesterday at 53*. I have riding pants and that made a big difference.

Those will work if you plan on changing your head to a standard type GY6 head. The cam installs into the rocker assembly and then the rocker assembly, with cam installed, is bolted to the head on the 161QMK. The chain sprocket is bolted onto the end of the camshaft with two bolts so you can get to the C clip that holds the cam into the rocker assembly. Those cams will not work and the rocker assembly will not work with the 161QMK head.

I know that the heads are totally different than the standard GY6 head. They have a cooling chamber that goes between the top of the cylinder and the cam support. Certain parts are hard to come by, such as cams. I have read that they can be bored out to a 232cc, but I have never seen a kit or any other info on how to do it. All though a 232cc motor in a 150 sized motor would be supper cool......

I have read 16-22 foot pounds for the 150cc. Make sure you have the right setting and that the tool is working properly. Make sure you tighten the bolts in a cross pattern incrementally.

I think the Asians got us beat on personalizing their scooters.

The one on my sons scooter was fairly easy to take off, just take off the two bolts. I would use some lock tight for sure. Seems the factory used some kind of lock tight, it was white and pasty on the threads anyway. Just make sure you do not over tighten those bolts. They are fairly small so it would not take to much to strip them. thanks! was able to get them loose with a little effort. did you replace your cam and if so where, which one ? for future reference if I ever need to get one... No problem.
I never was able to find a cam. We resorted to using the old cam. One of the lobes was damaged, but it looked like the rocker did not ride over the damaged area so we reinstalled and crossed the fingers. He has a few hundred miles on it now and it is still running fine.

Scrappy has parts,but according to him he sells cams that will work with 80 mm stud spacing models and traditional 76 mm spacing. On left of scrappydogscooters.com look to gy6-200 gy6B dedicated page and check out all the parts. Good luck.... I love my 161QMK. Hope yours is running soon! Yes, that is where we got the head and the gaskets. Gaskets where on back order at the time took 2 months to get the gaskets. He wanted to be able to ride without waiting so I tried the copper gasket trick. It is a old school way to save gaskets. We had nothing to loose so I decided to give it a try. Still running fine.
The problem with the cam is that the gear has to be removable to get to the C clip that holds the cam into the rocker assembly. There is also a anti kick back tab on the opposite side of the gear. I looked high and low for a cam, but could not find one. In my sons case the cam was damaged some.

I just replace a head on my sons 161qmk. That is a totally different head design than a standard GY6. Not to mention a real pain to find parts for. GY6 cams will not work with this design. The two bolts on the gear holds the gear to the cam. To install remove those bolts. First I would put the engine at TDC before putting the head on. That way you do not have to fiddle with the chain so much. Then you can bolt the cam housing to the top of the head, made sure your cam lobes are facing down towards the top of the head. You should at this time notice that the bolt holes in the cam should be nearly lined up with the top of the head. Now you can slide the gear into the chain and line up one of the lines on the gear with the top of the head. You might have to mess with the links a bit, but one of those lines should be parallel with the top of the head with the motor in TDC. Not sure what the WY stands for and I am not sure if it matters. The only thing I can think of is that it is a visual to see if you are in exhaust stroke or compression stroke. I installed my sons with the WY showing once installed. When we worked on my sons we found parts hard to locate or on back order. Finally had to reuse the old head gasket to get him back on the road. We used copper spray gasket to get him rolling again. Still running fine. itistheride.boards.net/thread/7662/oil-leaking |

That is nice. Bet it makes the scooter ride a bit smoother too.

Both brakes should operate the brake light.
